Siemens SIMATIC S7-1500 Digital Output Module DQ 32x24VDC/0.5A, 32 Channels, Sourcing (PNP), Push-in Front Connector, Diagnostics | 6ES75221BL100AA0

This digital output module stands out with its 32 sourcing (PNP) channels, each rated for 0.5 A, making it ideal for high-density 24 V DC control tasks in SIMATIC S7-1500 systems. Unlike basic output modules, it provides single-channel diagnostics for wire-break, short-circuit, and supply voltage issues, enabling rapid fault localization.

Highlights

• 32 digital outputs, 24 V DC, sourcing (PNP)
• 0.5 A per channel, 4 A per group (8 channels per group)
• Single-channel diagnostics: wire-break, short-circuit, supply voltage
• Configurable substitute output values for safe state behavior
• Push-in front connector (40-pin) for tool-free wiring
• LED status indicators for each channel, plus module status and error

In daily use

The module integrates seamlessly into S7-1500 stations via the backplane bus, with isolation between channels and the bus for reliable operation. Short-circuit and overload protection safeguard both the module and connected actuators. Firmware updates can be applied in the field, ensuring future compatibility. The compact design and DIN rail mounting simplify installation in control cabinets.
